Yes indeed Read section 4 in the data sheet found here. http://ww1.microchip.com/downloads/en/devicedoc/39582b.pdf Even if you program in C you have to set some other registers as shown in example 4-1, in the same data sheet

 

I have set all the port A as a digital
i put ADCON1 = 0X06;

the result is the not function as smooth as the portb as output. is that any configuration that miss writing in the datasheet?

 

Post your code Then we may see how to help you.
